After receiving my new to me 95 GT. I've been addressing some TLC issues that the car needs. One of the things I've been doing is scanning the car for codes, fixing the problems, then scanning further. The last code that I did was a KOEO scan to test cylinder contribution to engine performance. I'm happy to say that the report came back 90 = all 8 cylinders are contributing equally to the engine. I wanted to make sure that the test outcome could be repeated so I performed it again. The same results came back; 90. My question(s) is this; Can I trust the scanners results enough to where I do not need to do a compression check? Is this scan something one would do in addition to a compression check or in leu of one? Any brainiacs out there have feed back?
